biostatistician

I have a set of data of patients from different places who have had the same operation to remove their appendix. A small subset of the these patients have come back with cancer in the appendix. I calculated the incidence rate by dividing the total number of appendectomy/cancer of appendix and represented it as a percentage. I would like to compare the incidence rates of cancer of the appendix by state.

Sample data looks something like this

State Total number of appendectomy Cancer in appendix Incidence
State A 500 25 5%
State B 2000 20 1%
State C 1000 5 0.5%
State D 50 1 2%
State E 5000 75 1.5%
All states 8550 126 1.47%

I want to suggest that by staying in a specific state places a patient at higher risk for cancer and maybe there's an environmental risk factor for this. Is it possible for me to say that a state has a significantly higher or lower incidence rate than the other states?

Or is there another way to represent the findings?

Thank you.
